Rail Vehicle Hose Holder with Sword Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In double-articulated rail vehicles, hoses between car body holders sag due to the length difference caused by tilting, leading to chafing against bellows, especially when the contact wire height restricts adjustments.
Innovation Solution
A holder with a plate-shaped element and a sword extending between receptacles, featuring fixing elements that increase the hose span and reduce sagging, along with a cylindrically symmetrical suspension element for enhanced flexibility and fatigue resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hose length is increased to accommodate car body tilting during curves, crests, and dips, then the hoses have sufficient freedom of movement, but the hoses sag considerably and rest on the bellows causing chafing
Solution Approach 1:
The holder divides the hose support into multiple segments: the plate-shaped element with receptacles provides primary support, while the sword with fixing elements creates additional support points. This segmentation reduces the effective span of each hose section, preventing sagging while maintaining overall flexibility through the slidable suspension element.
Solution Approach 2:
The sword extends in the first direction (perpendicular to the plate-shaped element) to provide support between the receptacles. The suspension element's axis extends in the second direction (perpendicular to the sword), creating a three-dimensional support structure that reduces sagging in multiple directions simultaneously.
2Object-affected harmful factors
If additional brackets are added between the supports on car bodies to reduce hose span, then hose sagging is reduced, but the device complexity increases
Solution Approach 1:
The invention merges multiple support functions into a single integrated holder structure. The plate-shaped element with receptacles and the sword with fixing elements are combined into one component that can be suspended from the crossbeam, eliminating the need for multiple separate brackets while providing comprehensive hose support.
Solution Approach 2:
The holder structure serves multiple functions simultaneously: the plate-shaped element with receptacles provides primary hose support, the sword with fixing elements provides additional intermediate support, and the slidable suspension element enables adaptive positioning. This multi-functionality reduces the need for separate components.
3Object-affected harmful factors
If the gallows are raised to reduce hose span, then hose sagging is reduced, but this is only possible when contact wire height is sufficient
Solution Approach 1:
The suspension element is designed to be slidable along the crossbeam, allowing dynamic adjustment of the holder's position. This adaptability enables the system to function effectively at minimum contact wire heights by optimizing the hose span according to the available space, rather than requiring a fixed elevated position.
4Object-affected harmful factors
If the hose length is reduced to minimize sagging, then chafing risk is reduced, but the hoses cannot accommodate the necessary freedom of movement during operation
Solution Approach 1:
By dividing the hose support into multiple segments (receptacles and sword with fixing elements), the effective span of each segment is reduced, minimizing sagging and chafing risk. The overall hose length remains sufficient for freedom of movement, but the segmented support structure prevents localized sagging between support points.

AI summary
The invention relates to a holder for a rail vehicle. The holder (100) according to the invention for a rail vehicle comprises a flat element (110) with at least one pair of receptacles (200), which are respectively configured to accommodate a hose, and is characterized by a blade (900), which extends in a first direction (X) that is perpendicular to the flat element (110), is disposed between the receptacles of the at least one pair and comprises fastening elements (910) for fastening hoses accommodated in the receptacles to said blade (900). The holder (100) according to the invention has the advantage that the span width of the hoses is increased by the additional fastening to the fastening elements (910). When the holder is used in a rail vehicle, the slack is reduced to such an extent that the hoses no longer rest on the bellows. This prevents fraying of the hoses, even at minimum contact wire heights.
